A court in Brisbane was told that the mother bought the drugs online from Canada and set up a web page saying that her daughter needed a bone-marrow transplant. Health workers suspected the girl was being poisoned and advised police, who searched the mother's home and found a pill crusher and online receipts for the drug, which can be used to treat various cancers including leukaemia and breast cancer.
Judge Tony Rafter, in sentencing, said the crime was "incomprehensible" and that the mother was seeking to gain attention.
"You must have been aware of the serious harm you were causing to your daughter", the judge said. "Your daughter must have experienced pain and discomfort."
The woman pleaded guilty to grievous bodily harm last October.
Catherine Morgan, her barrister, said the mother suffered from a rare mental disorder known as factitious disorder by proxy, which caused her to produce or exaggerate symptoms of someone in their care. The court heard she had previously faked symptoms to have her appendix removed.
The girl is now being cared for by her maternal grandmother.
